The PSEC4 custom integrated circuit was designed for the recording of fast waveforms for use in largearea time-of-flight detector systems. The ASIC has been fabricated using the IBM-8RF 0:13 μm CMOS process. On each of the six analog channels, PSEC4 employs a switched capacitor array (SCA) of 256 samples deep, a ramp-compare ADC with 10.5 bits of DC dynamic range, and a serial data readout with...

—In this paper, we address the architecture of multistandard simultaneous reception receivers and we aim to reduce the complexity of the analog front-end. To this end, we propose an architecture using the double orthogonal translation technique in order to multiplex two signals received on different frequency bands. A study case concerning the simultaneous reception of 802.11g and UMTS signals ...

This paper present proposal for fast testing method of AD converters aimed for estimation of INL as the error function and superimposed uncertainty based on two dimensional ADC error model. INL function is being determined by curve fitting of approximation function from the measurement of INL(k) in chosen code bins of the full scale range of ADC under test. Proposed testing method is suitable f...

This paper is focused in the effect of adaptive weighted non-linearity in speech coding. The results showed that the effect of adaptive non-linearity improves the spectral distance measure when compared to the system without non-linearity. Key-Words: Coding, Non-linearity, Hammerstein Model, Adaptation

In this article, we described basic properties of Riemann integral on functions from R into Real Banach Space. We proved mainly the linearity of integral operator about the integral of continuous functions on closed interval of the set of real numbers. These theorems were based on the article [10] and we referred to the former articles about Riemann integral. We applied definitions and theorems...

This paper presents design and implementation of a 9-bit folding and interpolation ADC using 0.35 μm CMOS C35B4 model under AMS-HIT Kit Library. The complete system consists of two main blocks. One of them is 4-bit flash ADC, which is based on the so-called threshold inverter quantization (TIQ) technique. This part forms the coarse part of the data conversion process. The second one is the 5-bi...
